Combined MIGHTEE and CHILES stacking yields log MHI = (0.32 +/- 0.04) log M* + (6.65 +/- 0.36) at z ~ 0.36, placing gas content between the z=0 and z=1 relations.

abstract
We distribute an easy-to-use mock catalog of galaxies with detailed neutral atomic hydrogen (HI) and auxiliary molecular and optical properties. The catalog covers a field of 10-by-10 degrees and a redshift range of z=0-1.2. It contains galaxies with 21cm peak flux densities down to 1uJy and is, within this flux limit, complete for HI masses above 10^8 solar masses. Five random realisations of the catalog in ASCII format (~4GB/file) and subtables with HI flux limits of 10u Jy (~500MB/file) and 100uJy$ (~30MB/file) can be downloaded at http://ict.icrar.org/store/staff/do/s3sax.

New constraints on the evolution of the MHI-M* scaling relation combining CHILES and MIGHTEE-HI data
Combined MIGHTEE and CHILES stacking yields log MHI = (0.32 +/- 0.04) log M* + (6.65 +/- 0.36) at z ~ 0.36, placing gas content between the z=0 and z=1 relations.
